'Be it known that 1, AUGUST): PACHE, a

subject of Switzerland, residing in the city of New York, borough of Manhattan, county and State of New York, have 1nven'ted acertain new andnseful Timing Ap paratus, of which the following. is a specifi This invention is a timing apparatus, and

the object of the invention is to provide a device particularly applicable for setting off explosives at the expiration of a prede termined period.

The invention may be briefly stated as erabodying a time train, means controllable by the time train for setting off the explosive, and means also associated with the time train for determining the period of time to expire before-the operation of the means for setting oil ,the explosive.

In one of its practical forms, the invention embodies a timetrain with which is associated a spring-actuated hammer adapted to set off a percussion-cap. Means is provided for maintaining the hammer in a restrained position until it is desiredto fire the cap, which means is governed by the time train, and means is also associated with the time train for precluding the release of the hammer restraining'means until the expiration of a predetermined period.

Features of the invention, other than those specified, will be apparent from the hereinafter detailed description taken in conjunc tion with the accompanying drawings.

In the accompanying drawings, have illustrated one practical embodiment of the invention, but tlleconstruction shown there" in is to be understood as illustrative, only,

Referring to the drawings, A indicates a time train which is herein shown as of any well known and conventional form of alarm clock. X

a designates the main spring of the clock, Whereas a indicates the spring which actuates the alarm. Alarm spring a is mounted upon the usual arbor 0, and one end of said spring is secured to the post aiof'the frame of the clock, all as clearly shown in Fig. 8. In the form of the invention shown, alarm spring arbor (6 is provided with a threaded shank a at its rear end, and, onto this shank, is secured an extension axle B which projects beyond the rear plate 13' of the up paratus. Near the free end of axle B are plates b which are engaged by the interiorly threaded hub of a restraining member 0.

Positioned intermediate restraining mem-- ber (J and the rear plate B of the apparatus is anaxle encircling sleeve 0, loosely mounted on the axle and provided at-its outer end. with the hub of a laterally projecting arm E, hereinafter termed the hammer. The other end of the sleeve 6 projects through the rear plate B, and a collar c is threaded.

thereon to preclude longitudinal movenient of the sleeve. Hammer E is adapted for pivotal movement upon axle l3 and may be brought, under conditions hereinafter specified, into juxtaposition with a slot e of a firing chamber 6? fixed on the rear plate-B. Within firing chamber 6 is removably pd sitioned a hollow firing barrel 6, from one side of which project substantially radial openings into which may be inserted one or more percussion-caps or cartridges 6 The relation of the parts is-such that, when firing barrel 6 is in proper position within* firing chamber 0 the percussiongcaps 6 will be in juxtapositionwith the slot 6 in chamber; 6,- see Fig. 7. Accordingly, if hammer E is swung with suiiicient force into said slot, it will engage with the ends of the percussion-ca s and cause them to be exploded. The mec anismfor accomplishscrews 0',- and the other'endE-of which,

i to normally maintainsthe hammer in slot 6 cured to thewall of a stationary'casing e by means of a screw 6. Spring e serves clockwise direction from the'position shown 7. in dotted lines in Fig. 4, to engage with the forward edge of hammer E and rotate the same against thetension of the spring 6 into theretracted, full-line position of said figure. To readilv carry out this operation, a suitable key, not shown, is provided, which may be positioned upon axle B and, being fixed against relative movement therewith bv a pin 0 may be operated to rotate said axle in a clockwise direction. the key is thus actuated, plate C and hammer E may be moved to the retracted position shown in full lines i'n Fig. 4, means heingprovided for locking the hammer in this position, against the impelling action of its spring. This means is shown in the form of a latch F which is normally maintained in engagement with the periphery of thehub of the hammer by a spring f and is provided with a finger f adapted to enter a shouldered depression formed in the circumference of said hub. Thus, when the parts have beenmoved to the retracted position, finger f will enter the depression and. lock the hammer against the action of the spring. Bearing in mind that axle B is a continuation of the'arbor a "for the alarm spring a of thetime train, it will be manifest that, when the key is turned in the manner specified, the arbor a will be rotated and the spring a placed under tension.- As is usual in alarm clocks, the mechanism of the clock serves to lock the arbor against return rotation until the time has arrived at which the alarm has been set to operate. Consequently, hammer E will be locked in its retracted position by the latch F, and restraining plate C will be maintained in its retracted positionby the conventional mechanism of the time train.

In the well known formof time train illustrated, the releasing of alarm sprin a is governed, through well known mec a-' ,nism, from an oscillating arbor g, from Which projects a laterally extending arm 9.

Arbor g is normally precluded from oscillating by a lever which cooperates with arm 9' and normally holds the same against movement.- -However,.when the arm is released' by the lever and thus allowed to oscillate, the spring is released and the arbor o to which it is secured, is rotated thereby. 'According to the present invention, the arm g ofoscillating arbor g is normally engaged and netained against movement by a lever G pivoted to the front plate of the, apparatus as by the screw 9' When 1 face of the dial.

with arm Q, but said means is operable, under certaln conditions, to allow of the movement of said lever out of engagement with said arm. This means constitutes the time-selecting devices next to be described.

In the clock employed in the carrying out of the present invention, the hour hand and the mechanism for rotating the same about the dial of the clock are omitted and, .while the arbor I, which normally actuated the m nute hand, is retained, said minute hand is replaced by a stouter hand or pointer i. Arbor I extends through the front plate a" of the apparatus,- through a supporting s ider 2' and through the center of the dial pointer 2' being positioned adjacent the A Means are provided for, normally holding the lever in engagement Intermediate front plate z" and spider i and fixedly positioned upon arbor I, is a disk L. M and N are positioned in parallel relation to arbor I and at spaced distances therefrom, in such manner that, at their back ends, they are journaled in the front plate 73 of the apparatus, while their forward ends are journaled in, and pass'through, the spider 5 In a manner similar to arbor I, each ofthe stub-shafts referred to is provided with a fixed disk m,'n, respectively, positioned in different planes relatlve to the face of the front plate, the disk L resting substantially against the front late, disk m overlapping disk L and in c ose relation therewith, and, correspondingly, disk n overlapping disk m and in close relation therewith. Each of the several disks referred-to is provided in its circumference with a depression, and said depressions are designated l, m and n for the disks L, m and n, respectively, Positioned on front plate 2' as at o, isa swinging carrier O which is provided with a plurality of fingers o, o and 0. These fingers. are formedrigid with the-carrier member 0, and their free ends are adapted to normally engage with the periphery of each of the several disks referred to. power arm of the lever. G, which governs the-operation of the oscillatory arbor g, engages with the rear of said carrier member and ope ates to maintain fingers 0' o and 0 in ng gement with the periphery of said iisks by exerting a slight pressure thereon. Asllong as'any one, of the fingers remains in engagement with the outer circumference of its respective disk, thelever G will preclude the operation of the oscillatory Moreover, stub-shafts At the same time, the

shaft g,'but, at that time when all of .the

disks are so positioned that the notch in the circumference of each is in juxtap bsition with the corresponding finger of the carrier member Q, said carrier member will turn Lis fixed to the minute arbor I, said disk. will rotate'at a tuned speed,'2'. 6., it will 'turn to a certain number of angular de ,io g'rees for every minute. In order to prop-' erly measure these angular degrees, the dial J isprovided with a cooperating pointer i fixed to arbor I. The dial, as shown in Fig. 1, is provided with circumferential designations, each of which marks one minutes time in the travel of the oi'nte'r i, and the relative position of the pointer to the notch Z of the disk is such that, when the pointer registers with the designation 0, corre- 26. 1; ending to the sixty minute mark on the e ock, the notch Z" will be in juxtaposition With its (:06 rating finger 0' of the carrier fl nember. ith this relation of parts, it will befmanifestthat, if the pointer iis inthe osition shown in Fig. 1, as designating ap- ,roximately 32% minutes to go before reachg the zero mark on'- the dial, it will take I iilst 321} minutes before the notch Z will be i rought into juxtaposition with its coopafii stating finger 0. If, at the expiration of that time, the notches of the other two disks arein cooperative relation with their corre- I spending fingers, the alarm spring a will be released as described. Thus, the time in 35 minutes" to elapse before theoperation of the alarm spring a may be readily timed from the face of the dial, simplymoving the pointer around the dial to register the number of minutes which it is desired to 40 elapse. f

' From the foregoing, it will be apparent that disk L corresponds to the minute periods of time and will, accordingly, be ereinafter.termed the minute disk. As will hereinafter be explained, moreover, disk m isthe hour disk, while disk a is the day disk. Thus, disks L, m and n determine theminutes, hours, and days, respectively, of the time to elapse before the operation of the device, and, for the propercarry ing out of their function, all of these disks should operate in timed relation;

Depending fromthe under side of disk m are a plurality of spaced pins'm which are 5'5 twenty-four in number, corresponding to the twenty-four hours of the day, and upon arbor I is positioned a laterally extending finger 71 0f such length that,once in every rotation of the arbor I, saiqLfinger 59 will engage with one of the pins and turn disk m through ;-an angle equal to one "twenty-fourth of one complete rotation.

' Consequently, when the. minute handhas:

traversed the dial twenty-f eur times, the ,hour disk will'have made one complete roa e m me i ster with the corresponding"fingers of the 75 carrier member, is the alarm spring. a released- Accordingly, the disks may be said, in a measure, to resemble the tumblers of a lock, all of which tumblers must be in'a predetermined position before the lock can be actuated. i

To preclude inadvertent movement of the disksm and n braking devices are provided, herein shownas small knobs m n", which engage with the pins of the respective disks and are resiliently maintained in such posi tion by spring-impelled stems m n, respectively. These braking devices exert sufficient pressure upon the pins to preclude' inadvertent movement, but are not suiiicient to retard the movements of the respec tive parts at the proper timesi In order that the hour and day disks may be properly adjusted to'cover any predetei mined time expiration, the shafts M N are extended through apertures in the dial J, and each shaft is provided on its free end with a suitable knob m for shaft M and nfor shaft N. To facilitate the setting of the disks, plates P'Q are fixed to the respective shafts M and N so as to immediately underlie the dial. On plate P are the numerals 1 to 2d, inclusive, desi mating the hours of the day, and on plate a are the numerals 1- to 8, inclusive, designating the corresponding number of days. In the dial are formed two apertures over'eaeh plate. Over plate P are the apertures HM meaning hour's andminutes, and I,meaninghours. Over plate Q, are the apertures D, meaning days, and DH meaning days and hours. Through these apertures-the operatormay readily ascertain the position of the day and hour disks, while he is setting ,the, same through the medium of the knobs w and Assuming that the operator desires to set the apparatus hereinbefore described so that it will become effective atthe expiration of one day, one hour, and ten minutes, the following operations are performed: Knob n is set to show the numeral 1 through the the pointer i is positioned at the zero point on the dial. When thus far regulated, the clock is set for-one day and two hours. Since only one; day, one hour and ten mintheporhteeianow manu- 13c tension of its coiiperating to the day disk, end of the clock and, consequently, the day disk ally moved in a clockwise direction to subtract fifty minutes of the two hours, thus leaving the tinle of one day, one hour and ten minutes. Having thus set the apparatus, is allowed to run underv its own power. During the ten minutes next ensuing, the finger i on the minutearbor will engage with one of the pins m (If the hour disk and complete one hour of the original two hours to which this disk was set. As the time train continues to rotate the finger i atthe rate of one rotation an hour, the hour disk willbe given one complete rotation in a day and, for each complete rotation of the hour disk, the finger m cooperating therewith will give one impulse allotted time, all of the disks will be brought into such position that the notches in the circumferences thereof will be in juxtaposition with-the carrier; member 0, and alarm spring a will be released. lVhen the alarm spring is released, it-immediately operates its arbor a", with theresult that the restraining plate C is moved in ac'-, cordance therewith in a counterclockwise direction from the full-line position shown in Fig. 4 to the dotted-line position therein.

owever, restraining plate C is provided with a pin 0 which extends inwardly from the plate and into the plane of the latch F,

so that, as the restraining plate is rotated as l is in the path of the pin described, latch 0 Consequently, as the spring a unwinds, the pin comes into engagement with the latch and forces the same back against the spring f, to such extent that the finger f" is disengaged from the, depression f of the hammer. Remembering that the spring 6 has been previously placed under tension by thekey, it will be manifest that, as soon as the hammer is'releaseil ill the mannerdescribed, said spring will become active in rotating the hammer, with considerable force. from the retracted. full-line position shown in Fig. 4 to the firing position shown in dotted lines therein. As the hammer thus comes into engagement with the surface of the percussion-caps e in the firing barrel, these caps will be exploded.

the hammer may be placed in retracted position, 6. set, and the time-selecting devices also set at any one time, to be operative at the-expirationiof any desired period. I have illustrated, in the drawings, all eight-day ls shown as limited to an eight-day period, although, manifestly, this period might be 'of much greater duration, simply depending upon the addltlifm' of more numerals to the.

plate Q. i

In the description of the operation hereinbefore set forth for a period of a day or from affecting the movement withthe result that, at the,

aperture of the dial, and, in this position, its as notch will be juxtaposed vwith the corresponding figure 0. to term the neutral, position, the finger m cotiperating with the hour disk is precluded of the, day disk the pins n as by the om1ssion of one of finger may pass shown in Fig. 6, so'that said In thisfwhich I prefer idly past the day disk without affecting its position. In the preferred embodiment of themvention, the clock is adapted to cover days, hours, and minutes, though, manifestly, the day disk n, and even the hour-disk m, may be eliminated, if the apparatus is to be for periods equal to, orless than, an hour only. Thus, a device for timing periods of less than an hours duration may be en tirely devoid of the hour and day disks, 9.

This greatly simplifies preferable, when short quired.

' It will, of course, be understood'that the spring a, which drives the time train, may be wound. up in the usual manner by applving akey to its arbor r (Fig; 4) in and well known manner."

The device be employed for various uses, the specific embodiment shown being that of setting off explosives through the -medium of percussion-caps. The explosive to be fired may be positioned directly .within the firing barrel e, which may be extended any desired length for the reception of such charge as is necessary, or said percussion-caps may be operated in the firing barrel to set 011 further devices, which in turn-operatebn the explosive to be fired. E. 9., in dynainiting excavations, the percusslon-caps may serve to simultaneously light a. plurality of fusesbroadly novel as is commensurate with the ap ended claims.
